摘　　要：The photodegradation of diclofenac in the absence/presence of cetyltrimethyl ammonium bromide,crystal violet and humic acid under simulated sunlight has been studied.Under the study conditions,it is apparent that cetyltrimethyl ammonium bromide and crystal violet concentrations inhibit effects on the photodegradation of diclofenac.Humic acid has no distinct effect on the photodegradation of diclofenac.Crystal violet has an obvious antagonistic action for humic acid and a similar antagonistic action between cetyltrimethyl ammonium bromide and crystal violet.Cetyltrimethyl ammonium bromide and humic acid have synergistic effect.An antagonistic action is present between cetyltrimethyl ammonium bromide,crystal violet and humic acid.Moreover,a simple linear model which describes the obtained results is shown.The photodegradation of diclofenac in the absence/presence of cetyltrimethyl ammonium bromide, crystal violet and humic acid under simulated sunlight has been studied.

Humic acid has no distinct effect on the photodegradation of diclofenac. Crystal violet has an obvious antagonistic action for humic acid and a similar antago- nistic action between cetyltrimethyl ammonium bromide and crystal violet. Cetyltrimethyl ammonium bromide and humic acid have synergistic effect. An antagonistic action is present between cetyltrimethyl ammonium bromide, crystal violet and humic acid. Moreover, a simple linear model which describes the obtained results is shown.
